Abstract

Electrochemical reduction of phenylglyoxylic acid on silver cathode was studied in aqueous buffer solutions using voltammetry, cyclic voltammetry, chronoamperometry and controlled potential electrolysis techniques. Voltammetric studies have shown that while two reduction waves are formed around neutral pH, only one wave is formed at acidic and alkaline pH. The two waves are due to the reduction of the carbonyl group present in the phenylglyoxylic acid molecule and phenylglyoxylate anion. Chronoamperometric study has confirmed the cyclic voltammetric data as well as the earlier observations about the reduction of phenylglyoxylic acid which is mixed controlled at acidic pH and diffusion controlled at neutral and alkaline pH. Mandelic acid was the reduction product obtained in the controlled potential electrolysis
